Environmental Due Diligence
Strategic Environmental, Health & Safety Insight for More Insightful Transactions
Environmental, health, and safety (EHS) risks are a critical factor in mergers, acquisitions, and divestitures yet they are frequently underestimated, not considered, or delayed until late in the transaction process. These hidden environmental liabilities can reduce asset value, delay closing, or lead to long-term regulatory exposure and liability.
As a trusted environmental due diligence consultant, Odyssey helps operations, buyers, sellers, investors, and lenders identify and understand EHS risks before they become costly surprises. Our due diligence services deliver clear, actionable insight that supports informed decision-making at every stage of a transaction.
We combine regulatory expertise, operational experience, and business-focused risk evaluation to uncover environmental obligations that impact valuation, compliance, and long-term asset performance.
What Is Environmental Due Diligence?
Environmental due diligence is the process of identifying environmental, health, and safety risks associated with a property or operation prior to a transaction. It evaluates potential contamination, regulatory compliance gaps, workplace safety or personnel health-related issues, and other environmental liabilities that may affect financial, legal, or operational outcomes.
Environmental due diligence is commonly required for:
- Property acquisitions and divestitures
- Mergers and acquisitions
- Financing and refinancing
- Portfolio risk evaluation
Comprehensive Environmental Due Diligence Services
Odyssey delivers scalable due diligence solutions for single assets and multi-site portfolios, aligned with lender, investor, and regulatory expectations.
Phase I Environmental Site Assessments (ESA)
